Memory Leak causes zt_pri_error

Hello we are using D210P card with 1 E1 ISDN line.

Asterisk 1.4.20.1 Zaptel 1.4.9.2

Server Memory is DDR2 2 Gb.

After 10 hours running the memory was used up. Asterisk didn't crash, but the voice quality is been corrupted.

in the CLI there are error messages:

chan_zap.c:8250 zt_pri_error: !! Got reject for frame 87

Before same server was running with TDM card, the memory didn't leak.

When your system memory usedup, Linux will swap memory to disk frequently, thus system will be very slow. you have to keep the memory not used up. may be you have some memory leak issue in software?
