Explanation of error26601 in the process of LoadRunner pressure testing

This time, in the Xiaoqiang performance test class A1 led by me, there was a child in the pressure test of our project who accidentally discovered the problem. I took the opportunity to sort it out.

The general error prompt is as follows:

Action.c(240): Error -26601: Decompression function (wgzMemDecompressBuffer) failed, return code=-3 (Z_DATA_ERROR), inSize=17, inUse=0, outUse=0 [MsgId: MERR-26601]。

Analysis:

Looking up the data found that this and buffer capacity, roughly because the packet is too fast, the server did not come and respond, lr did not download the data packet once, and then press the packet when the error.

Solution:

1. Add lr_auto_head("Accept-Encode","gzip") to the script;

2. Set--perfernce, increase the value of network buffer size
