<p>I think these messages are reported by the Linux kernel SCSI
initiator. From drivers/scsi/scsi_error.c:<br>
</p>
<p><br>
</p>
<p><font face="monospace"> if (sshdr->asc == 0x29) {<br>
evt_type = SDEV_EVT_POWER_ON_RESET_OCCURRED;<br>
sdev_printk(KERN_WARNING, sdev,<br>
"Power-on or device reset occurred\n");<br>
}</font><br>
</p>
<p><br>
</p>
<p>That kind of error should not happen while SCST is running. Was
the SCST server perhaps rebooted? Is this a standalone or H.A.
SCST setup? If the setup should survive power cycling of the SCST
server, consider using multipathd at the initiator side.<br>

Also, how is daemon like srpt_mlx5_0-1 lunched? I saw over 1400
srpt_mlx5 daemons lunched at different days. Is that a problem?</div>

<p>It is known that the ib_srpt driver can create a large number of
kernel threads. I agree that 1400 threads is too much so I have
created a bug report to track this and assigned it to myself:
