Hello All, at RWTH Aachen, Germany, we are experiencing frequent kernel freezings of our (a bit older) data servers when using (SL5,) the xfs file system and NFS4 with i386 data server architectures. No problems with 64 bit servers.
>From the /var/log messages we think that the problem is due to a smaller stack >size for the i386 kernel as described here: http://www.mythtv.org/pipermail/mythtv-users/2005-May/089314.html Any chance that for future SL kernel upgrades 8k instead of 4k stack size is used also for the 32 bit architecture (kernel parameter CONFIG_4KSTACKS=n) or any idea how to cure the problem ? In our opinion ext3 is not a very good choice for big data servers in case of fs crashes. I found this issue discussed already in Jan 2006 on this list but I wonder whether there was any progress during the last four years. Thanks & cheers, Thomas. -- Mit besten Gruessen/With kind regards, Thomas Kress, RWTH Aachen, III.
