[rbak-nsp] SEOS Problems question

Tue Mar 27 19:40:47 EDT 2012

Hi Sebastian

we have SE400 and 6.1. (old ... i know) software (now 6.5.), we faced similar problems... actually 2 in particular:
first was one 10-ge card kept crashing on weekly basis... sometimes more and the only solution to fix it was to reboot whole server or shutdown the card , pull it out of chasis, insert it again then power it on again. Ericsson stated that this was due to NAT used in network as it was consuming the memory causing the card to crash. although as they state this should be fixed totally on .11 version but who knows.

the second case was the same card used to reset by itself and an error similar to "multiple bits error" used to appear on log... this was caused by defective RAM and the only solution is to replace the card itself.

so if you are on NAT you might want to check on first case as it would be a good candidate.

Best Regards
Karam

Both cards crashed, it seems that card with active subscribers crashes. 
Below you'll find summary of our crashes - based on crash reports I've 
collected:

11.1.2.3p1/20120103_145943_crashSlot02Ippa.gz
11.1.2.3p1/20120113_003527_crashSlot02Ippa.gz
11.1.2.3p1/20120114_213150_crashSlot02Eppa.gz
11.1.2.3p1/20120125_102418_crashSlot02Ippa.gz
11.1.2.3p1/20120214_184623_crashSlot01Eppa.gz
11.1.2.3p1/20120214_213239_crashSlot01Ippa.gz
11.1.2.3p2/20120220_060409_crashSlot01Ippa.gz
11.1.2.3p2/20120313_192413_crashSlot01Ippa.gz
11.1.2.4/20120326_021727_crashSlot01Ippa.gz
11.1.2.4/20120326_220920_crashSlot01Eppa.gz

At start we used only 10x1 in slot 2, then we moved everything to 4x10. 
No we have "uplinks" on 10x1, and subscribers + some other things on 4x10.
Other interresting thing is that crash occurs (mostly) only once after 
full system reload and after that it can work for almost a month (jan.25 
- feb.14) without any problems.

Regards,
Sebastian
