logrotate was ineffective.

following apache httpd config seems to disable logging of mjsonrpc requests. note that we cannot filter on the "mjsonrpc" string because 
Request_URI excludes the query string (ouch!).

#SetEnvIf Request_URI "^POST /?mjsonrpc.*" nolog 
SetEnvIf Request_Method "POST" envpost 
SetEnvIf Request_URI "^\/$" envuri 
SetEnvIfExpr "-T reqenv('envpost') && -T reqenv('envuri')" envnolog 
 
CustomLog logs/ssl_request_log "%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x \"%r\" %b" env=!envnolog
