October 5, 201213 yr Running 5.0 RC8a Syslog is attached I'm not exactly sure what happened, but it appears I lost power at some point last night. This morning I was unable to access the browser GUI, and I kept getting 'connection refused' messages with telnet. Pinging resulted in 'host is down' messages. After a combination of hard restarts/power cycling, I was able to ping the server successfully, and it looked like telnet might be working until the server all of a sudden went offline (still wasn't able to access the GUI). Anything useful in the log? Any suggestions? syslog.txt
October 6, 201213 yr Author Just ran 3 full passes over the last ~4 hours and came up clean. I went ahead and swapped the ram with a stick from a known working system and I'm still experiencing the same issues. Console access has been spotty as well. I was able to log in and copy that syslog over, but half the time I try and enter log in and/or pass and it just sits there hung. It takes quite awhile to get to the login prompt as well. I'll go ahead and continue running MemTest tonight, but any other suggestions and/or fixes? Thanks for the help so far!
October 6, 201213 yr Author Alright I've run MemTest overnight (7 passes) and the RAM has still come up clean. What else could it be? What do I need to do to get running again? Reinstall unRaid?
October 6, 201213 yr Basically, one or more of your add-ons is using up all available memory. The kernel out-of-memory process (oom-killer) is killing off programs in an attempt to free what it needs. You can look at what it is using by typing free -l usually, "low" memory runs out first. The solution, find the add-on that is using up all your memory and either get a fixed version that behaves better, or disable it completely.

October 6, 201213 yr Author Interesting, thanks for the help, I'll start diving in and disabling what I can. One question though, I setup a swap file when setting up MYSQL (and my hunch tells me MYSQL might be the culprit), so shouldn't that resolve any memory issues (though performance would be quite bad when using the swap file I imagine)?

It depends... A swap file will not help with some "low" memory issues if they cannot be freed. (In other words, it can only swap out what it is able) Also, are you sure you did not create the swap file in RAM? (using it up potentially?) The MYSQL data file, or TEMP files could do it too... if created in RAM. In any case, you might want to look in the customizations sub-forum for updated versions and assistance. This is not a general support issue, but a customization one.
