Hi everyone,
Hoping someone might be able to point me in the right direction. For the past couple of days the gwia on one of my GroupWise servers is accumulating several TCP/IP Read errors and it's still rising. Most of the SMTP threads are at a constant busy state. I've bumped the threads up to 20 and now it's at 50 but that doesn't seem to help. They are still busy. I don't see any stuck messages either. It appears that most messages are going through but on occasion when I test using telnet command I get the following error
421 Service not available, closing transmission channel
Connection closed by foreign host.
Only changes on that server have been OS and OES patches. I applied some on 10/13 and 10/14.
Any help would be appreciated. 
OES 11.2
GroupWise 2012 SP4  - gwia-12.0.4-120531
