Fatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 32 bytes) in /usr/local/itapps/www/html/processmaker/gulliver/thirdparty/pear/Log.php on line 446

I tried to claim an unassigned case, even cases of different processes, i will get this error.

Has not happened before. Anyone encountered this?

I've never seen this. What version of PM? What is your OS and what version of PHP?

According to the code, it is trying to execute a backtrace and open a log file. You probably have a very big log file. In your php.ini file, try this setting:

Code: Select all

memory_limit = 1024M

Does that solve it?

[keyangl]

Its CentOS 7
3.0.1.7-community
PHP 5.4

i've tried putting to 2048 and it still errors this way.
Have been using for many years, first time encountering this.
You mentioned the log file, which log file to be exact? maybe i can just purge that?

[keyangl]

I cleared the logs in shared/log
but it still errors the same way
Any ideas?

Since you can't display the backtrace, it is hard to know where the problem is arising, but if your backtrace is in an infinite loop, then it could use up all the memory.

Try this. In /usr/local/itapps/www/html/processmaker/gulliver/thirdparty/pear/Log.php, line 443, change the code from:

Code: Select all

    function _getBacktraceVars($depth)
    {
        /* Start by generating a backtrace from the current call (here). */
        $backtrace = debug_backtrace();

To:

Code: Select all

   function _getBacktraceVars($depth)
    {
         return ('', '', '', '');
        /* Start by generating a backtrace from the current call (here). */
        $backtrace = debug_backtrace();

What do you see now?

i added that then i got this:

Code: Select all

Parse error: syntax error, unexpected ',' in /usr/local/itapps/www/html/processmaker/gulliver/thirdparty/pear/Log.php on line 445

i changed it to

Code: Select all

array('','','','')

Then i got the same error again but in a different file:

Code: Select all

Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 64 bytes) in /usr/local/itapps/www/html/processmaker/workflow/engine/classes/model/om/BaseUsers.php on line 361

Does this problem only occur with a single case, or does it occur with all cases in a single process or with all processes?

How much space do you have free on the harddrive's partition where PM is installed? I have seen strange problems with RAM memory allocation when a ProcessMaker server runs out of space in the harddrive's partition.

[keyangl]

It occurs with all unassigned cases from all processes.
Opening an already claimed case and routing it in the inbox is fine.
Only when im trying to claim a case, no matter which user, will it give this error.

/usr/local/itapps is the path, but its only using 51% of the total space.

Any ideas?

Undo the code changes that you made in the Log.php file. Maybe your APP_CACHE_VIEW table is corrupted. Go to Admin > Case List Cache Builder and click on "Build Cache".

If that doesn't solve it, then I suggest creating a new workspace and import a couple processes and see if the same problem occurs in the new workspace. If that works, then the problem is probably in the database.
Run the processmaker database-verify-consistency command on your workspace.
You can try to fix it by running the processmaker upgrade command.
You can also try exporting your workspace and import it into a new workspace.

If the database doesn't appear to be the problem, then you could try overwriting the source code by upgrading to a new version of ProcessMaker. Finally, you can file a bug report at bugs.processmaker.com and see if the developers have any suggestions.
