Hi
I experienced some odd instability recently on PCP 7.0.1 with LMS 8.1.1,
and had the dreaded empty library. A rescan didn't work so I restarted
LMS and I could browse the network mount again but the PCP kept dropping
off the LAN, even after a reboot, even though ping was working fine.
Another reboot and it all seems to be behaving itself again, thought it
occasionally times out on the web UI, which I don't see normally.
Are there any diags I should look for? How does one detect a dodgy
sdcard for example? I can only see dosfsck under Beta functions, which I
presume is no use for linux filesystems.
Nothing of note in LMS log file.
I checked in dmesg and found some post-boot exceptions and backtraces
reported which might not be good - and I don't see them on my other
PCPs.
