I had an issue with a stack of 3750s before as well. Turns out that it was
logging to a file on flash:
logging file flash:syslog xx debugging
The x was a ridiculously large number. This ended up filling up the
file system over time and cause errors much like the ones being described
here.
Do you have any sort of logging turned on like this?

Not hardware issue. We've got loads of 3750Gs running for years without
problems. Most on 12.2(55)

Just curious... has anyone had issues with memory leaks on 3750Gs? We
have had nightmares from a 4-switch stack of 3750G-48TS's (IP Services).
Runs for months, then you try to write mem and get memory allocation
errors and it fails. It progresses a bit further and you can no longer
get serial console, telnet, or SSH either.
Have had several suggested workarounds and software upgrades; we're on
almost bleeding edge (15.something SE4, while SE5 is latest). I'd tell
you what version it is if I could get into it :)
Used to just reload and it would work another few months, but tonight's
reload we immediately couldn't get into the serial console (%%Low on
memory - Try again later).
Starting to think this is a hardware issue as we haven't seen it on any
other 3750s, wondering if anyone else has seen this.

Hi folks, Xander,
Why is the SVD disabled by default on 4.3.x what is the benefit of pushing
all the mac addresses, prefixes and labels for all the VRFs to all the LCs
please?
Alrigh I understand that you get like 4M of FIB entries on Typhoon LCs so
the question is who cares right?
But still I'd like to know the true reasoning behind it, might the SVD be
causing some issues in some circumstances please.
Thank you.
adam

Hi listers,
We have a 7200 with NPE-G2 that has happily acted as a border router for
around a year. We are only using the onboard interfaces.
On Sunday night the device randomly rebooted and the reboot cause shows as
System returned to ROM by error - a Software forced crash, PC 0x6FC26C
from show version.
When the device came back up everything appeared okay and there was nothing
in the logs after the reboot (we weren't exporting syslog for this one).
There were no CPU spikes in the monitoring system. Traffic levels look
pretty normal.
This is the IOS version running: Cisco IOS Software, 7200 Software
(C7200P-ADVIPSERVICESK9-M), Version 12.4(4)XD4, RELEASE SOFTWARE (fc1)
According to the Cisco docs about Software forced crash we need to use
the Output interpreter tool for this. We do not currently have support for
this unit and it will be replaced with an ASR1k
