| |
I have encountered a serious problem with nfs under 2.2.20pre8 and pre9.
after some ammount of time (2 weeks under pre8, only a few hours under pre9) most/all processes accessing an nfs filesystem go into unkillable disk sleep, and the kernel starts spewing:
kernel: nfs: task 22509 can't get a request slot
over and over again endlessly. since processes using the filesystem are unkillable i am unable to even forcabily umount the problematic filesystem, seemingly the only way restore order is shutdown -r now :(
the server is an x86 running 2.2.19, knfs, with userland utils version 0.3.1. the client is a powerpc running 2.2.20pre8 or pre9, both exhibit this behavior. 2.2.19 on the client does NOT exhibit this problem.
note that this seems to mostly get triggered on my daily cronjobs, which simply tar up /etc to a tarball on the nfs filesystem, its really not that intensive (/etc is only about 2.6MB or so). i have other machines doing the same thing without incident (they are currently running 2.4.9).
the server displays no unusal symtoms or any log entries that would indicate trouble.
both client and server are using NFSv3.
please CC me any replies as i am not subscribed to l-k. thanks.
