Subject: Re: Elogd crashes on search 

Stefan,

I cut the log in two parts w/o modifying the content and the search runs. It seems that the size of this entrie 426 is closed to a limit (as during testing, i met a message after clicking save to recompile elog to increase a size of something), so it could be the problem.

I reduced the entrie size by extracting the last part in a new entrie and it seems to be OK.

The old size was 250099 bytes. New size is 240084.

I hope this will be OK.

Regards

Looks like. Can you dig into the database file and have a look at that entry? Or send me the file containing that entry (together with your elogd.cfg)

At #5, there is message_id=426 . You think it's this elog entries # 426 that is the source of crash  ?

Hi Stefan,

My previous dump is useless as your elog-debuginfo rpm is stripped.

So i rebuild elog w/ -g , reinstall it and activate core generation. I restst a search of "test" and get this in gdb corefile .

Is it better to find problem ?

Does it help you ?

The only way for me is to reproduce it. Could be corrupted data file, or config file. Try with a new logbook with the same configuration, then add logbook files one by one until it happens.

Laurent Jean-Rigaud wrote:

Hi Stefan,

The problem seems to be specific with our logbooks. Maybe one of the file is corrupted or bad string encoding ?! But how to find the source of the problem ?

Any way to improve debug log ? (using debug level = 9 + logfile)

Also, do you have a procedure to debug ELOG with debuginfo package installed to have more informations in trace ?

.

Laurent

 

Stefan Ritt wrote:

Do you see the same problem on this server here?

If not, then it must be related to your specific configuration. You have to teach me how to reporduce the error in order to fix it. Best would be a minimal elogd.cfg which causes the error.

OS: CentOS 7 x86_64 up2date with RPM 3.14 x86_64

  • Connexion to ELOG
  • open one logbook and click search,
  • input "test" and click "Search" : BOOM
  • Firefox can not connect anymore on ELOG.

The crash is met with several words now ("test", "post", "4.5", are the one i know). We use a mirror server and the problem appears also on it .

NB: the hangs appears on EL6 x86_64 server with customized RPM built by myself. I retry with 3.14 SRPMS avalaible from ELOG site with same results. Idem with last GIT version. So i tested on EL7 with official RPM x86_64 (not suitable for EL6 as it needs GLIBC_2.14) before to open this ticket.

 

Terminal traces on server side follows.
