I've been running this configuration for 5+ years on previous releases. After upgrading the serving (ctl) side 13.0p7->13.1, I have started getting these warnings/errors intermittently (<1-14 days between occurrences): Server (ctl) side: (Repeats a handful of times, all with the same timestamp= .) | Aug 23 21:08:41 kernel: WARNING: icl_soft_conn_new_pdu: failed to allocate soft PDU | Aug 23 21:08:41 kernel: WARNING: 10.0.1.2 (iqn.1994-09.org.freebsd:): connection error; dropping connection Client (iscsid) side: | Aug 23 21:08:42 kernel: WARNING: (iqn.): connection error; reconnecting | Aug 23 21:09:08 kernel: (da4:iscsi2:0:0:0): WRITE(6).

The server here was updated to 13.1 first, and errors first appeared in that state (13.0 client; 13.1 server), and have persisted in the current (both 13.1) configuration. 10 GbE X540-AT2 on both ends.
