The hard limit is in code, NGX_MAX_ERROR_STR which is defined to
2048. The limit is due to use of static buffer for logging
errors, it's used to avoid allocations in error logging path (as
allocation may fail, especially if we are trying to log allocation
error).

The access log line size isn't limited. The buffer= argument is
to reduce number of write() calls, which is helpfull in case of high
load.
