# sk173836 - SMEM memory allocation failures for "ws_gzip_filter_alloc" may be recorded in CPview, along with "parsing error" logs in SmartLog

## Symptoms

- * SmartView Tracker logs show blocked or accepted traffic according to engine settings:  

  "`HTTP parsing error occurred, blocking request (as configured in engine settings)`"  

  "`HTTP parsing error detected. Bypassing the request as defined in the Inspection Settings`"  

* 
  **Failed memory requests** below **CPview** -\>**Advanced** -\> **Memory** -\> **SMEM-Failures** show "`ws_gzip_filter_alloc`" with "`No memory`" as the cause.

## Cause

When HTTP/HTTPS data is compressed with gzip and reaches the Security Gateway, it must first be extracted.  

The extracted information is stored in a buffer, where its default size is 1048576 (1M). You can change the default size with the **wsis_gzip_chunka_output_buf_size** kernel parameter (see below).  

In some scenarios, the buffer size is not sufficient in high load environments, resulting in allocation failure.  

Based on the point of failure, a retry occurs. If the extraction fails, a parsing error can occur, resulting in the allowing or dropping of the connection as configured in the engine setting and the corresponding log.
