Dear Community Members,
++++++++++++++++++++++ Known error report ++++++++++++++++++++++
We’d like to inform you about a know error identified within the
OTRS 2.2.3 release. On Unix / Linux systems running OTRS 2.2.3
that known error causes memory to 'disappear', the system might
freeze, load increases or error messages like "No free space left
on device" might pop up. Note, windows users are not affected.
PROBLEM DESCRIPTION:
-----------------------------------------------------------------
Public FAQ: # 4200252
http://faq.otrs.org/otrs/public.pl
Due to a bug in the log backend of OTRS 2.2.3 the shared memory
of the system is filled with entries which are not freed
anymore. You can check your system with the command:
ipcs
Use it as root to display your system's ipc facilities:
# ipcs
------ Shared Memory Segments --------
Key shmid owner perms bytes nattch status
0x0056a4d5 494665728 root 660 488 1
0x0056a4d6 494698497 root 660 131072 1
------ Semaphore Arrays --------
Key semid owner perms nsems
0x00000000 163840 www-data 609 1
0x0056a4d5 247365633 root 660 1
------ Message Queues --------
Key msqid owner perms used-bytes messages
If you see entries starting with "0x00000000" your system is
affected by the memory leak in the Log backend and you are
strongly advised to address this issue as described below.
SOLUTION 1:
-----------------------------------------------------------------
To solve the problem download the attached Log.pm file and
copy it into the Kernel/System directory or your OTRS
installation, replacing the existing file. You need to restart
your Web server for the change to become effective.
Note:
Use the linked file in the Public FAQ: # 4200252 only for OTRS version
2.2.3. This is the only release having this particular problem.
