I just upgraded an OI server to Omniosr151018.
I am having some intermittent issues with the smb service with Windows

Does anyone have a dtrace script/suggestions to try to isolate it.
I am running wireshark one of the traces I have show SMB service
response time for NT Create AndX calls is very high, with a avg of 24
seconds.
The other commands are good:
Read AndX avg 0.0007
Query_File_info avg: 0.000404
Qeury_Path_Info avg 0.000512
Network seems fine, iperf runs at wire speed.
Large files through smb are at wire speed.
I have tried both SMB and SMB2.
iostat doesn't reveal any bad disks, nor are the disks busy, they are
actually pretty idle.
Pool is only at 30% full
There is a 40GB arc, and the arc hit rate is very high, so everything
really is in arc
No dedup.
Just to be more clear here, the delay is caused when launching an
application. If I copy the file from Windows explorer, the performance
is OK.
I looked at my wireshark trace when launching the application and I
noticed that the NT Create AndX SRT for a lot of the files is 30
seconds. A round number like that normally means it is triggered by
something. Now I just need to figure out what.
thanks,
Geoff
