httpd-2.0.59 woes

We're trying to move from apache 1.3.x to 2.0.59 and I'm running into
difficulties. Under any kind of load, apache dies and the logs are
filled with this error:

[Mon Jul 09 11:13:41 2007] [error] (22)Invalid argument:
apr_global_mutex_unlock(jk_log_lock) failed
[Mon Jul 09 11:13:41 2007] [info] [client 10.37.74.20] (32)Broken
pipe: core_output_filter: writing data to the network
[Mon Jul 09 11:13:41 2007] [emerg] (22)Invalid argument: couldn't grab
the accept mutex


Also, without even requesting https, I get the following errors in the
error_log:

[Mon Jul 09 11:12:45 2007] [debug] ssl_engine_kernel.c(1769): OpenSSL:

error, 11 bytes expected to read on BIO#4046e948 [mem: 4048f2b8]

Any insight?
