When the hardware is oversubscribed for compression operations, the 4200v platform can display errors. When the error occurs, the system posts /var/log/ltm errors similar to the following: - crit tmm7[18648]: 01010025:2: Device error: (null) qa_dc_get_flat_buffer: Allocation linked list is empty - err tmm7[18648]: 01010004:3: Memory allocation failed: qa_dc_dev_init_buffer_list: Couldn't allocate memory for buffer list. - err tmm7[18648]: 01230140:3: RST sent from 10.1.13.207:41906 to 10.1.1.51:80, [0x171d345:974] {peer} Compression error (Out of memory)

This occurs with compression on the 4200v.
None.
Compression on the 4200v platforms now behave properly in these cases.
