Here's one possibility:

If the TEC server is not up or not accessible when the TSM server
starts, the Tivoli event logging will be disabled. You can restart it
with the "BEGIN EVENTLOGGING TIVOLI" command. 

This has been happening to me sporadically because sometimes the TSM
server starts before the Tivoli TEC gateway starts (they both run on the
same physical machine). Apparently TSM does not try to contact TEC again
after the initial failure.

Subject: Tsm & TEC trouble

Hello,

I configure TSM integration with TEC, all work fine, but episodically
TSM stop sending events (without any error messages about this). 
This situation occurred two times:
1. TSM 5.2.2.0 and TEC 3.9FP02 on same mashine with RH 7.3. (After
restart TSM all work)
2. TSM 5.2.2.0(or 5.2.3.0, I can't remember) on Windows 2000 SP4 and TEC
3.9FP02 on RH 7.3

Any ideas?

Thanks
