Hello everyone I started getting the following messages in the /var/log/messages file a couple of days ago. kernel: stuck on TLB IPI wait (CPU#0) ....... kernel: stuck on TLB IPI wait (CPU#3) The second one is very interesting since there are only 2 CPU's in the box. (I am assuming CPU#0 & CPU#1 ? ) The hardware is an IBM x330, with an IBM ServerRAID 4M, with 2, 18 gig drives and 2 Gigs of Mem. OS :Suse 7.0 Running oracle 8.0.5STD Please note that I am NOT running ReiserFS. I did a search on google and most of the problems seem to have been with ReiserFS. I did a top on the server and there doesn't seem to be any run away processes (that was also reported as being a problem). Can anyone help me? Has anyone seen this before? Is this a possible hardware problem? memory? Disk drives? Raid controller? Please let me know if you need more info. Thanks Dany Allard
