SG300-10MP keeps going down!!!

[codystokes]

Hello,

We are in an organization of 80 users with 5 Sx300 series switches with the latest firmware (1.2.7.76). The network is mostly flat with all switches feeding into a Cisco ASA5505 acing as the primary gateway for Internet Access. Only our two 48 port POE switches have an additional vlan configured for the VoIP phones.

We have one SG300-10MP that is powering 5 Cisco Aironet 1024N's that keeps crashing. A couple weeks ago it went down twice in one day. I updated the firmware and it did not have any hiccups unitl today. This issue has been consistent since we installed the switch in April. Originally the issue seemed to be caused by too much bonjour traffic causing a buffer overflow (we have over 100 Apple products). Since I updated the switch I have not seen any bonjour buffer overflow errors. Instead I get the following error when it crashes:

2147424534 2012-Sep-05 15:12:28 Emergency %SYSLOG-F-OSFATAL: FATAL ERROR: tExcTask: ABORT DATA exception ***** FATAL ERROR ***** SW Version : 1.2.7.76 Version Date: 19-Jul-2012 Version Time: 17:54:43 Instruction 0x18 Exception vector 0x10 Program state register 0x80000092 %SNMP-I-CDBITEMSNUM: Number of startup configur ation items loaded: 133 %LINK-W-Down: gi1 %LINK-W-Down: gi2 %LINK-W-Down: gi3 %LINK-W-Down: gi4 %LINK-W-Down: gi5 %LINK-W-Down: gi6 %LINK-W-Down: gi7 %LINK-W-Down: gi8 %LINK-W-Down: gi9 %LINK-W-Down: gi10 %LINK-I-Up: gi9 %LINK-I-Up: Vlan 1 %LINK-I-Up: gi1 %STP-W-PORTSTATUS: gi9: STP status Fo

The CPU and PoE supply are far from being overloaded. Can anyone tell me what this is and what it means? Can't seem to find anyone else with the same problem and it is extremely frusturating! Thanks in advance.

I am still experiencing random restarts.  Having not heard anything lately I updated the firmware on the affected switches to

1.2.7.76, and the number of restarts seems to have increased.  2 out of 3 of the affected switches also now seem to reboot themselves in tandem.

Find log entries and *uncorresponding* uptime reports below.  This is now becoming a real problem for us.
