PANIC: Cannot attach to shared memory region, due to insufficient access(probably owned by another user or group)

Dear all,

unfortunately I experienced my first crash of our productiv Domino-Server

(Server rans very fine with normal workload for weeks, at the moment of

crashing the workload reached a peak but not more than 280 users…)

  • HP Proliant ML 570 - dual 2,8 Ghz Proc (Hyperthreadind deactivated)

4 GB RAM

  • Suse Linux Enterprise Server 8 with SP3

  • Domino 6.5.1 with Suse ExtensionPack

Please find below the serverconsole at moment of crash… and a workaround

from IBM Side…

Anybody experienced the same and tried out this IBM Notes.ini settings for

Memory ?

By the way: I am using the Domino Extension Pack from SUSE and "more than

1000" users is NOT activated in domino-script, because we only have maximum

600 Users here…

Should i activate this basically regardless how many users i have on

machine ??

Any help/hint/tipp is really highly appreciated… !!

Thanks and best regards,

Alex Hofer

I found now two workarounds from IBM

  1. http://www-1.ibm.com/support/docview.wss?uid=swg21095911

I have used these workarounds but we are still getting the Panic errors about every night. I am open for more suggestions.

I am getting this same error on Windows platform, I found an article where this is a known issue however it does not mention a solution ETA.http://www-1.ibm.com/support/docview.wss?uid=swg21205715
