CMDTUX_CAT:1380: ERROR: Message queue blocking prevented delivery

652398Dec 8 2010 — edited Dec 8 2010
Today, I changed a Tuxedo application (server) to the product systems(One master and two slaves). Only a small changes in code. But after a period of running, there are many errors in ULOG:

CMDTUX_CAT:1380: ERROR: Message queue blocking prevented delivery, Qaddr = 583902

And then, the server is died. After restart the server, this will happen again later.

I don't know why this happens? Thx.

Hi Bill,

This is happening because the BRIDGE process received a message from the network and was unable to place the message on the intended IPC queue. This could be because the server handling that message is backed up, or the system IPC resource settings are too low. Please check the recommended actions in:
