[OpenIndiana-discuss] MPT SGL mem alloc failed

[Liam Slusser]

Hey All -

I'm having a similar problem to https://www.illumos.org/issues/2994

Although that bug #2994 has been closed with "issue disappeared in a6/a7".
 I'm running a8 and having a similar issue (see crash from below).  Looks
like my dump volume is too small (i'll fix that) but past that anybody have
any ideas?

Dell R420 64g ram
LSI 9207-8e HBA firmware 15.00.00.00, bios 7.22.01.00
2 x Dell MD1200 (12 x 4T SAS) arrays

This server exports a few raw volumes via fibre channel and nothing else.

This thread is similar:
http://openindiana.org/pipermail/openindiana-discuss/2012-July/008694.htmlbut
there was no solution given.
