https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D266302 John Baldwin <jhb@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jhb@FreeBSD.org, | |mav@FreeBSD.org, | |trasz@FreeBSD.org --- Comment #1 from John Baldwin <jhb@FreeBSD.org> --- This message means that an internal call to uma_zalloc to allocate a PDU structure failed on the server side. This just means that your server is u= nder memory pressure, but that it handled that condition gracefully. You might monitoring the memory usage for the "icl_soft_pdu" zone in vmstat -z output= to see if it seems like it is growing super large. Alternatively, it might be that you need to set a limit on the growth of the ZFS ARC to leave enough R= AM free for your existing iSCSI connections. Limiting the ARC might have effe= cts on other workloads, so you'd have to decide how to balance that based on yo= ur needs. --=20 You are receiving this mail because: You are the assignee for the bug.=
