Summary
The process for WAN acceleration is crashing with certain messages in logs, up to multiple times daily.Overview
When using acceleration on Exinda devices, it is possible to see a process crash for the WAN Acceleration process ('wmd'). This process is the process for acceleration that handles putting everything and taking everything from the WAN Memory partition on the device, including compression.When failing, one of the following sets of messages can be seen in the Logging (Configuration > System > Logging):
- pm[2086]: [pm.NOTICE]: Output from wmd (pid 29567): terminate called after throwing an instance of 'boost::exception_detail::clone_impl<CompressorException>'
pm[2086]: [pm.NOTICE]: Output from wmd (pid 29567): what(): LZ4 Decompression failure {decompress@common/compression/CompressorLz4.cpp:66}
- pm[2086]: [pm.NOTICE]: Output from wmd (pid 6123): what(): Decoder process invalid message type:12 {process_queue_item@codec/Decoder.cpp:413}
