Hello
My Galaxy instance suffers from 'MySQL server has gone away error'. This
error appears if the last web request was more than ~30-60 sec ago. The
full traceback follows at the end of this message. If the same request
is resent, everything is OK. My universe_wsgi.ini config file is set up
as recommended for mysql. All timeouts on the database server itself are
set well above 1min.
This occurs both on etch and lenny Linux 64 bit nodes. The python
version is 2.4
I would be helpful for any suggestions. Can move to postgresql, but
rather stay with mysql.
