APR Buffer NullPointer Error

Dear All

I am deploying application (Tomcat 8.0.22, JDK 1.7.79, Solaris, SPARC, APR 1.5.2) and observing multiple erros while its communicates with client software (error presented below). It looks like that error happens while application writes output buffer. Any suggestion what is going wrong? Might it be resources limitation on OS level (was configured based on Oracle recommendations already).

Probably more relevant to the tomcat users mailing list.
