Issue

  • We acquired mod_jk from EAP 6 downloads and are trying to use this in RHEL 7's httpd 2.4 package. This yields an error like the following upon start up:
Cannot load modules/mod_jk.so into server: /etc/httpd/modules/mod_jk.so: undefined symbol: unixd_set_global_mutex_perms

Environment

  • Red Hat Enterprise Linux (RHEL) 7.x
    • Apache httpd 2.4.x
