Possible Memory Leak - FW 1.4.9

I haven't found this reported on the forms for the 1.4.9 firmware, but I believe there is a memory leak somewhere.

I've got a few WS-12-250-DCs across my network and I'm seeing the free memory all both of them slowly drop over the period of about 10 months.

Well considering we are on version 1.5.0 or v1.5.1rc7 try upgrading the units and see what happens.

v1.4.9 is closed an no further development will occurr. However a lot of people are using v1.4.9 and not reporting this.

Also there are security holes in v1.4.9 so maybe if your switches are accessible by web they are hacked?

I have some switches using v1.4.9 that have been up for over a year.

I'm showing memory leaks in 1.5.0. One device that's been up 111 days. Originally had 38% memory in-use post-reboot, now 51%. It's slowly trending up for sure.

I have several switches that are up for over a year. It's hard for me to get much more than that as I have to constantly upgrade some units to test and I also want the security patches in the newer firmware.

Eric did say memory will grow a bit over time as the switch uses it for stuff (technical terminology) but there is no memory leak that will cause a problem. We had a real memory leak that did cause an issue many versions ago but was fixed.
