This is a reccurent issue (at least once a day) :
On an OSX 10.10.1 server with fms 220.127.116.11, fmsed service is running, console shows no "PSOS" client running, but any calls to psos return the 812 error.
We have to restart fmse when it occurs.
This issue also occured on fms 14.
Logs says fmse is stopped while it shows up in the process list of the activity monitor (so we can't monitor it)
The server as many actives client connections (45-60 clients on normal days) as well as cwp connections
