We have been running it on a 8500 for about a week with a 1000AP load and noticed no major issues. We also have it on a WISM2 with no issues. Both systems connecting back to PI 2.1.1

For engineering builds, you need to ask TAC for them. If you have a good relationship with your local Cisco wireless SE, he/she can probably get it as well. I only have the build for the 5508. Jeff >>> John York 09/05/14 7:27 AM >>> The only 7.6 choices I see on the download site are 7.6.130.0, 120.0 and 110.0. Is 7.6MR3 the same as 7.6.130.0, or does TAC have to give that to you?

I'm running 7.6.120.12 engineering build on 5508 - We're just about done swapping all of our AP's to the 3700 series, and with students back, they've been rock solid. Hundreds of 802.11ac clients running around, and 802.11n performance is far better vs the 1252 series we replaced. There was a problem in 7.6.120.0 with webauth - that was fixed in 7.6.120.6, but introduced another webauth CPU hog issue. That was this resolved in 7.6.10.12. Not sure if 7.6MR3 includes the webauth CPU issue fix or not, thus I'm going to stick with the engineering release for now.

TAC gave us an engineering build of 7.6.122.9 which resolved that issue, then our eduroam network started having issues keeping clients connected with Client Band Select enabled. Fortunately, the old APs were just disabled while we were rolling this out. I installed 7.6MR3 on the 5508, which resolved the band select issue in my test AP I stood up, but I'm leaving the 3700's in the aforementioned building turned off until we get through the first two weeks of our semester start. Also, food for thought. According to our TAC engineer, 5508's and WiSM-2's use the exact same code. As I'm told, validating using a 5508 WLC should mimic exactly that of production WiSM-2's. Cheers.

I experienced a few of them that caused high cpu and controller crash and they were webauth related. I would recommend 7.6mr3 and not 8.0 unless you have specific need for the newer features it has in it. I’m running 7.6mr3 on 5508’s and 2504’s and have some HA pairs and so far it seems to be pretty stable.

Is anyone seeing controller crashes on 7.6.120.0 with a high load? We upgrade to 7.6.120.0 in May, but haven’t had a real load (over 5,000 clients, say) until this past two weeks. We had “something” happen on Friday. We did do a “therapeutic reboot” on Saturday morning (at oh my God it’s 3:30 in the morning!). However, today it repeated. While investigating, we discovered the primary in one of the clusters apparently failed and went into maintenance mode. However, the active “secondary” still showed standby hot, so we did a failover – which caused an outage (uh oh). While consoled in, we got the maintenance moded primary back up, and was bringing the secondary back up, when we found this: pmallocProcessMemoryCorruption called by file(rrmSocket_wlc.c), line(128), for size(2048), failureType = (4) this entry's previous access was by: file(capwap_ac_sm.c), line(7393) (pmallocProcessMemoryCorruption): pmallocGenericCrashInfo=(++PMALLOC_POISONED_AREA_CORRUPTION) (pmallocProcessMemoryCorruption): thread ID(349= (349256224)) (pmallocProcessMemoryCorruption): current access file name(rrmSocket_wlc.c) (pmallocProcessMemoryCorruption): previous-access file name(capwap_ac_sm.c) pmallocProcessMemoryCorruption called by file(rrmSocket_wlc.c), line(128), for size(2048), failureType = (4) this entry's previous access was by: file(capwap_ac_sm.c), line(7393) (pmallocProcessMemoryCorruption): pmallocGenericCrashInfo=(++PMALLOC_POISONED_AREA_CORRUPTION) (pmallocProcessMemoryCorruption): thread ID(349256224) (pmallocProcessMemoryCorruption): thread name(Unknown task name, task id = (349256224)) (pmallocProcessMemoryCorruption): current access file name(rrmSocket_wlc.c) (pmallocProcessMemoryCorruption): previous-access file name(capwap_ac_sm.c) Dumping a core. This can take a few minutes... Controller crashed ....Queue Woken up jiffies = 4295262648 Obviously, that is bad (and yes, we’re opening a TAC case). tl;dr Has anyone else seen oddities with crashes on 7.6.120.0, and if so, did you upgrade? To 7.6.130.0, or 8.0.100.0? I’m running 8.0.100.0 in the lab, but light load. (which is what we did on 7.6.120.0 since May)… Thoughts? Opinions? Respectfully, Danny Eaton Snr.
