Online Meeting Center/Meeting Room 7.5.1 CF1 Solaris


Hi, All
Our sametime server OS is solaris; sametime meeting version is 7.5.1CF2.
we got the problem "Users are dropped from Sametime meetings at random intervals" for times and times.
many user are affected by the problem, suddenly dropped from the meeting, even just logged in the meeting.
we got the error log from summary.diag like this:

we referred to the IBM doc(http://www-01.ibm.com/support/docview.wss?uid=swg21384169) and added Notes.ini parameter debug_pd_nagle_off=1, but no effective result. the problem is still happen day by day.

I considered to do "enable debug for the Sametime meeting server" as IBM doc told, but seems the way is only for windows server.

what is the possible cause of this problem, how can we resolve it?

Any idea is helpful and appreciated.

thank you in advance!
