I wonder if it'd also be interesting to see the kernel/svcgssd interactions when it's failing. If there's strace options that'll give you all the I/O data..... >From the strace man page: it looks like strace -oTMP -e read=a,b,c -e write=a,b,c pid-of-svcgssd should do it, where a, b, c... are the file descriptors of any of the files named "channel" under /proc/net/rpc. You can find those file descriptors with ls -l /proc/pid-of-scgssd/fd/ |grep channel Fun. --b. ------------------------------------------------------------------------- Using Tomcat but need to do more?
