SQL Error log Time Gap - sql

The question is more towards the possible causes why SQL error log stops logging. In my scenario, checked the System/Applications logs for any crash or service stopped events and it was all clear.
The last timestamp in the log was 8:53 Am and it straight away jumps to 6:50 PM, close to 9hrs of gap with no information. And Database connectivity issue with the application as reported starts around 2:40 PM.Snippet
Security patches were applied the previous day and the server was rebooted at 6:20 AM.
Ultimately, SQL services were restarted to regain connectivity.
I suspect the patch but Anyone has any idea how and why would SQL server stop logging?

So i have the same issue, the last log i have is from Saturday then nothing till we restarted it on Monday.
we also applied "updated with the Windows Update to SQL Server 2016 SP1 Cumulative Update (CU) 8 KB4077064"on Saturday
the last error i have is
"An error occurred while trying to flush all running Extended Event sessions. Some events may be lost."

SQL Server response time increasing

I'm currently working on updating an ERP called Sage 1000 to a newer version. The main change occurred along the upgrade is that the ERP solution and its database became on two different server. Ever since, The response time has significantly increased.
The part related to SQL Server is the following: whenever the time response problem happens, I restart the SQL Server service and it starts working just fine, at least for a couple of days until I have to restart it again.
Within the task manager before restarting the service I can see that it consumes nearly 17 to 20 gigabytes of memory witch is an insane amount even for a server run service, after restart, the amount of memory drops to a normal 2 to 3 gigabytes.
So my question is the following: in your experience what could be the cause of such abnormal behavior? Right now I created a planned task to restart the service everyday at 3:00 am, but it's not a radical solution.
Thanks in advance for your help,

SQL Server Maintenance Plan Not working - no errors

To put it simply. I have a SQL Server maintenance plan scheduled to run every Sunday at 8:02 am. This morning when I checked the jobs it says it was successful but it didn't actually run (yesterday on 5/20) it is still showing the successful message from the previous run on 5/13. The job is enabled and I cant find any errors associated with it in the logs. A bit stumped.

SQL Replication Error (On Server Agent)

I have created the new replication. Now what is issue I am facing:
When I go to ​start the 'View Agent Snapshot Status' Its just start working and First line shows "Starting Agent" and just keep working, working and continuously working.
..
After sometime it show the following message:
"The replication agent has not logged a progress message in 10 minutes. This might indicate an unresponsive agent or high system activity. Verify that records are being replicated to the destination and that connections to the Subscriber, Publisher, and Distributor are still active."
I try the following solution that I found, I have increased the value of #HeartBeat_interval property of distributor from 10 to 30 but no success.
I have Sql Server 2008 R2.
any help will be appreciated really.
May be this will help to someone else:
I did the following changes and my replication is working perfect.
1 - Job username and Job password must have full access and permission of windows.
2 - You must be logged In to user that you will use in the replication script to create replication.
That's all.
Thanks!!
I had the same behavior.
some of my articals are huge. while the replica's synch was over, the agent hanged up with the same message as yours.
after ~20 minutes it began running as expected.
I thought it is not not normal behavior, but after creating my second subscription, the error appeared again. it was gone approximately after 20 minutes.
I believe it is encounters high load of data (in case it is) and hangs up for while.
hope it helps

What would cause SQL Server to stop writing to the error log?

Error logs for our SQL Server instance are gathering a large amount of data (250k records in a month) all day, then all of a sudden stop at roughly the same time of day (9:15pm), though on different days of the week and at seemingly random intervals of days.
This corresponds to other issues on the server: 1) jobs that move files to shares on the database server fail 2) I am not able to access the server via any method (tried RDP and SSMS). Once the servers are rebooted, SQL Server comes up and SQL Server error logging resumes.
Windows Event Viewer doesn't show any notable error messages for System (the other event logs have wrapped already).
The error logs are being written to the D:\ drive, which has over 100GB free currently. The error log files are in the range of tens of megabytes.
Appreciate any ideas on what might have caused this or how troubleshoot it. Thanks!
The cause appears to have been a corrupted maintenance plan. I discovered this by correlating the timing of the lock-up to the times the maintenance plan was running. The lack of logging made this difficult to confirm. Guessing that at least some parts of it ran normally, but got rolled back on restart.
The current fix was to disable the maintenance plan and replace it with a collection of jobs that do the same tasks. I will likely recreate the original maintenance plan if the server remains stable for another week or two. If we stay stable past that point, it should solidly confirm the maintenance plan as the source of the problem.

SQL Server Agent Job is not running

I have a job that is supposed to run every 11 AM and 8 PM. About two weeks ago, it started to not respect the schedule. The "fix" that I found was to start the job manually and then the job would restart respecting the schedule for a while but eventually the issue reappears.
The big problem is that there are no error message what so ever. If the job fails, I am supposed to get a notification Email which I do not. In the sql server agent logs and the Job history, there are no errors. In the job history, I can see clearly that the job skipped the schedule since there are no entries. It looks like it did not even start as if the running time had not arrived.
The schedule is set to run everyday and there are no limits on how long it is supposed to run. The sql Agent is set to restart automatically if it stops unexpectedly.
Did anyone get this problem before?
Check the user which is used to run the job. Maybe the user password is expired or the user itself is no longer active.
