We are having major problems for some time with Unity. We are running 2.4.6 build 161, TSP 6.02b and Call manager 3.0(12). Unity will be running Ok and then gets sluggish, doesn't take voice mails or doesn't light the MWIs correctly . The problem seems to be centered around Unity thinking that the
Exchange server to which the users are homed has gone offline When I check the event viewer I see these types of errors:
This is usually the first error in the event viewer:
Exception occurred and handled in File: h:\commsvr\Sources\AvWM\AvWMMutex.cpp at Line: 157 - Error: 80040123H Call stack:
0x5DD470DD AvWM.dll: <unknown symbol>
0xFEDCBA98 <unknown module>: : <unknown symbol>
0x89ABCDEF <unknown module>: : <unknown symbol>
0x77D5298F RPCRT4.DLL: RpcRevertToSelf + 858 bytes
then this error:
Last Category An error occurred while trying to logon to MAPI mailbox 80004005: /o=NASA/ou=NSSTC/cn=Recipients/cn=MSFC/cn=SuessST.
I have a TAC case open D217771 and I sent the event logs to the Engineer.
We are not having any network problems so I really think something is corrupted in Unity or I am just not seeing a bad configuration mistake. This server has been in place for 2 years now and we have ALWAYS had some sort of problem with Unity.
I hope you can help.
