Bonjour,
SM> Seems like Innobase has introduced some timeout ( I do not see how) on
SM> the sleeping connections.
I've been trying a few other things.
When I run Mysql with Innobase, if no client connects, no "Warning
signal 14" messages in the error log.
Then I run a client which only logs on the server (no other
queries). I then have to wait a few seconds (not always the same
delay) before inevitably having some "Warning signal 14" messages.
One message each 2 seconds :
010326 15:09:16 Warning: Got signal 14 from thread 4
Always thread 4 (even if thread 4 doesn't exist, but I've seen
that while there actually was a thread Id 4).
So, 1 message each 2 seconds.
If I do "mysqladmin xxx" (ping, status, processlist) , there is a
pause in the writing of "Warning signal 14 messages" of about 4
seconds and then ... messages are back.
Then if I stop the client (so no more opened connections to Mysql),
error log still receives "Warning signal 14" messages, one each two
seconds.
If then I do a "mysqladmin ping or status or ..." , the "Warning
signal 14 messages" stop being sent to error log ... and don't come
back.
If I run 30 clients connecting (but doing no queries), I still have
messages about signal 14 and thread 4.
If I make my daemons start working (doing some update/insert
queries) then I receive Warning messages but not only from thread 4,
from other threads too.
Regards,
Alex.
