Description (partial)

1. g_spa process crash followed by LC reboot on SPA reload with ATM VC with full netflow scale

2. g_spa process will be blocked in IM when we reset the SPA full line traffic rate.

Resetting SPA with full line rate will cause any one of the above symptoms.

Scale: 16K VCs per LC ( 4 3XOC3 ATM SPAs with 4K VCs each) cofigured for full Netflow

On reloading a 3XOC3 SPA housed in a SIP-700 with the above mentioned scale, the g_spa process crashes followed by the LC going in for a reboot.

MARMOT_TXPA_INTFIFOECC2 interrupt in seen each time the SPA is reloaded.
