I know. There are some patches to fix that. These are proposed for backport to
2.2.x:
* mod_deflate: Rework inflate output and deflate output filter to fix
several issues: Incorrect handling of flush buckets, potential memory
leaks, excessive memory usage in inflate output filter for large
compressed content
PR: 39854
Trunk version of patch:

2.2.x version of patch:
Trunk versions work. For convenience of review I merged the patches
for the deflate output filter and the inflate output filter:

The patch for the inflate output filter requires the patch for the
deflate output filter.
Keep in mind that people.apache.org is currently down. I would appreciate if
you could test the patches and report back here.
