Last updated on SEPTEMBER 26, 2019

Applies to:

Oracle Collaboration Suite - Calendar - Version 10.1.2.4.10 and later
Information in this document applies to any platform.

Symptoms

OCAS generates an unexpected number of ocas.fcgi processes, causing many open connections to the calendar server and the server reaching the the maxsessions limit, which in turn causes users from not being able to login and spawn an new process.

The following error is shown in the $ORACLE_HOME/ocas/logs/ocas_log file:

--------------------------------------------------------------------------------

PID = <PID>
