-------------------------------------------------------------
There's a separate issue on fixing body factory, that bug talks about the 8KB
limit. We should not make this a configuration, rather, we should fix body
factory to not be this stupid :).
Btw, the log buffer size is useful, if you are logging a lot, it helps
buffering and doing larger writes instead of a lot of small writes. The fact
that it doesn't increase the maximum size per log entry it's not this
configurations fault.

> Key: TS-3213
> URL: https://issues.apache.org/jira/browse/TS-3213
> Project: Traffic Server
> Issue Type: Bug
> Components: Logging
> Affects Versions: 5.1.1
> Reporter: Sudheer Vinukonda
> Fix For: 5.3.0
>
>
> We have seen a flood of the below warnings in diags.log, despite configuring
> the log buffer sizes sufficiently large. This happens even when we turned off
> ascii logging. Upon further investigation, it looks like, the body factory
> code tries to resolve the body factory templates as custom log entries
> (since, they may embed custom log fields), but, there's a hard-coded size of
> 8K for the buffer size that does the log field resolution at
> {{https://github.com/apache/trafficserver/blob/master/proxy/logging/LogAccess.cc#L1449}}.
> This makes the configured buffer values useless and results in throwing up
> the flood of warnings.
> {code}
> -bash-4.1$ sudo traffic_line -m . | grep log | grep size
> proxy.config.log.log_buffer_size 26624
> proxy.config.log.max_line_size 106496
> proxy.config.log.ascii_buffer_size 106496
> {code}
> {code}
> [Nov 25 23:19:30.343] Server {0x2aeb9b5aa700} NOTE: Traffic Server is
> skipping the current log entry because its size exceeds the maximum line
> (entry) size for an ascii log buffer
> {code}
> A simple fix is to use one of the configured log buffer sizes (preferrably,
> {{proxy.config.log.ascii_buffer_size}}) instead of the hard-coded 8k.
