ISR runs out of memory

[nmdc.kzstan]

Hi,

ISR G2  (c2951-universalk9-mz.SPA.152-4.M1.bin) has 512 MB of DRAM. Periodically it runs out of memory:

Processor Pool Total:  248831896  Used:  244070796  Free:    4761100

I/O Pool Total:             58720256   Used:  44351072    Free:   14369184

1. Why "show proc mem" command shows less memory than 512 MB? Processor Pool (248 MB) + I/O Pool (58 MB) ~ 310 MB only?

2. *Init* process holds more memory than normal (202 MB). What may cause this?

Load an MD IOS version like 15.0M or 15.1M and check again.

Thanks, we rolled back to 15.1 and it seems ok for now.
