Hi nsaazn,
Your servers are complaining of low system resources.
From you logs, I see error 0x5AA logged repeatedly by the Lanman agent.
2013/01/31 01:35:01 VCS DBG_21 V-16-50-0 Lanman:MAIL3-Lanman:monitor:VLibNetbiosTable::GetActiveInterfaces returned 2, 0x000005AA
Using err.exe from Microsoft:
C:\>err 5aa
# for hex 0x5aa / decimal 1450 :
SQL_1450_severity_16 sql_err
# ALTER DATABASE command failed because the worker thread
# cannot be created.
ERROR_NO_SYSTEM_RESOURCES winerror.h
# Insufficient system resources exist to complete the
# requested service.
# 2 matches found for "5aa"
You can check if you have something using up memory, cpu, handles or threads. These are typically the items that would cause this kind of message.
Thank you,
Wally
