help .. calling VACUUM FULL ANALYSE via JDBC make my production server restarting ?!?!?!? Please help :-(

Hi all,

  I just try to put my first postgresql server in production... and *(^&% it not easy...  I am in a fix/tweak/optimize
cyclefor more than a month.  Normal but I be so happy when everithing will be stable ... so that was I!  Sorry I work
aloneso need to talk sometime ;-) 


My new problem: the doSchemaMaintenance (in the stack trace below) calls a VACUUM FULL ANALYSE on the db.  It seems
thatthis make Postgresql close the connection and rebooted?!?!   

It seems to be an intermitant problem since I launch again the command this morning and it works without problems.

Any idea what is the problem?  Is that a good idea to call vacuum via JDBC or it's just a plan to ran into problems?

Is that a common behavior that Postgresql reboot like this?  For now I don't think so .. an I need to restart the
applicationeach time:-( 

Any help will be appreciated!
Thanks
/David
