On B4450 blade, the avrd log receives constant error messages similar to the following in ltm.log/avrd.log: err merged[40445]: 011b0900:3: TMSTAT error tmstat_create_scripts: Resource temporarily unavailable. User timeout 5 is reached failed subscribe to avr_blade:


This causes an increase in tmstat memory usage.


Configuration includes: 1. DoS profile enabled for L7 and L3-4. 2. ASM policy is attached. 3. AVR profile with traffic capture is enabled, with remote logger profile. 4. Off-system processing is enabled.
