bktong Posted June 21, 2011 Posted June 21, 2011 All, I am sure this is not a new topic but I will ask anyway. I have been using my ISY for about a year now and in most cases, it's great until recently. I have been getting frequent lock up/freeze. I would have to do a hard boot to get it back. It happens about 1-3 times a month where I didn't see it that often before. I do have an ELK "linked" to the ISY. It's not due to rebooting ELK which I know causes ISY to freeze. Any ideas. I can't figure a pattern on when it happens. I'm running version v2.8.16. Thanks, bktong
Michel Kohanim Posted June 22, 2011 Posted June 22, 2011 Hello bktong, Sincere apologies for the inconvenience. First, please do be kind enough to upgrade to 3.1.3. Secondly, if you have ELK hooked up to ISY, AND IF you use ELK RP, that's when the unit locks up. This is a known issue which should be fixed shortly. With kind regards, Michel
bktong Posted June 23, 2011 Author Posted June 23, 2011 Michel, I knew about the ELK RP locks up ISY but I hardly use ELK RP. It sometimes happens in the middle of the night when everyone is asleep. I will upgrade to 3.1.3 and let you know. Thanks. bktong
Michel Kohanim Posted June 23, 2011 Posted June 23, 2011 Thanks bktong, please do keep us posted. Lately, we have also seen at least a couple of cases of EZxxx devices bombarding the network to the point that the PLM/ISY become VERY VERY slow to unresponsive. In case of ISY, you will see UDQFull which indicates queues are getting filled up. ISY recovers if EZxx is removed. So, if you have EZxxx devices, please check your error logs. Furthermore, you will find a lot of information in error log which might help with diagnosis. With kind regards, Michel
bktong Posted June 23, 2011 Author Posted June 23, 2011 I do not use any EZxx devices. You asked me to upgrade from 2.8.16 to 3.1.3, is there a known issue with 2.8.16 on freezes? Thanks. bktong
Michel Kohanim Posted June 24, 2011 Posted June 24, 2011 Hello bktong, Not really ... the main issue is that since our code base (point of reference for debugging) is now at 3.1.3 (and soon 3.1.4), it's easier for us to pinpoint/isolate issues. With kind regards, Michel
bktong Posted June 25, 2011 Author Posted June 25, 2011 Michel, Ok, it locked up again today (version 3.1.3 now) but the Error Log (pulldown from Tools tab) shows only entries from 5 hours ago. Since I have to do a hard boot, does it retain any memory right before it crashes? What log? bktong
Mark Sanctuary Posted June 26, 2011 Posted June 26, 2011 Not sure if it helps but I had a while back some SwitchLinc Timer switches that went bad which made the ISY lockup until I removed and replaced them with new regular SwitchLinc switches. I did not figure this out though until I unlinking a bunch of the switches from the ISY to systematically isolate the problem.
Michel Kohanim Posted June 26, 2011 Posted June 26, 2011 Hello bktong, I am so very sorry to hear. Would you be kind enough to do the following: 1. Please send me both your error as well as system logs (support@universal-devices.com) 2. If possible, remove ELK configuration from ISY (Configuration | System) by clearing out the IP address and port settings under ELK section With kind regards, Michel
bktong Posted June 29, 2011 Author Posted June 29, 2011 Michel, I will wait for the next crash and then I will send you both logs. I will leave ELK as is for now so that if it is ELK, you will see it in the logs. Thanks, bktong
