Re: Server Crash

[Fabio Pardi <f.pardi@xxxxxxxxxxxx>]

Hi,

what was running as PID 7471?

what happened before the first message at 10:29:52?

what is 'alarm clock' appearing at first line in the logfile?

still missing answers from my previous message:

/var/log/messages ?

how much ram on the machine?

what are the memory settings of postgres?

regards,

fabio pardi

Hi Fabio,

I understand your point, however i am in tremendous pressure to provide the solution.

I have attached the log file for review.

We have Red Hat machine and Postgres 9.1.13 version.

Appreciate for your response and help.

Hi Anjul,

please avoid cross posting over multiple mailing lists.

Also asking again does not help, and usually is counterproductive: members see a reply and they might put efforts on helping somebody who did not get a reply yet.

Please take good note of it.

About your problem:

I would suggest you to upgrade to a newer version, since Postgres 9.1 is too old and does not get updates any longer.

Besides that, not being a perl expert i cannot help with your procedure. I think anyway the problem might be somewhere else. I suspect that your server crashes and what you read there is only a consequence, not the cause.

Could you post any relevant log entry in /var/log/messages and maybe anything else appearing in the postgres logfile?

What kind of machine are you running on? can we have more specs?

How is your server configured?

regards,

fabio pardi

Hi All,

We have recently deployed couple of new plperl SPROC in our postgres production server and after that server start throwing error. Currently we are using postgres 9.1 and planning to upgrade with PG 10. 

But we are not sure if that will cause the same error in PG 10 as well. We really need help.

Error Message:

2018-06-21 13:43:29 EDT [22212]: [4-1] user=cmsuser,db=forte ,host=10.10.1.3,port=10.10.1.3(56601),id=5b2bdea5.56c4,line=4DETAIL:  The postmaster has commanded this server process to roll back the current transaction and exit, because another server process exited abnormally and possibly corrupted shared memory.
