Description

Getting regular panics on HAMMER FSs when transferring large quantities of data
over the network. initally saw the issue with NFS but eliminated that and now
seeing it with 'tar' piped across 'ssh'. was most prevelant when using USB or
FW storage but most recent test to internal IDE drive has thrown up the same
error.

NB: transfers are generally across unreliable links (i.e. wireless) and oft-
times, long stalls (i.e. minutes) occur -- most recent crash was after i had
paused a 'tar/ssh' transfer using CTL-Z.

NB: turning on crashdumps and re-executing tests but may take hours to fail -
any pointers in the meantime would be excellent.
