(6834364) Web Server 7 generates core dump when shut down if SUN LoadBalancer lbplugin is installed

• Description

  When Web Server 7.0 with lbplugin installed is shut down, a core file is generated. The core file contains something similar to the following:

  current thread: t@1 =>[1] __lwp_kill(0x0, 0x6, 0xfd5f3700, 0xfe822a00, 0xff36f338, 0x0), at 0xfd5c5bf0 [2] raise(0x6, 0x0, 0x20f04, 0xff34ba3c, 0xff36a000, 0xff36abdc), at 0xfd564bf4 [3] umem_do_abort(0x6, 0xffbff018, 0x6, 0x20e40, 0xff356ad8, 0x0), at 0xff349188 [4] umem_err_recoverable(0xff357b54, 0xa, 0x20d38, 0xfe8ae5d8, 0xff36d0e8, \ 0xff357b5f), at 0xff34932c [5] process_free(0x282468, 0x1, 0x0, 0x3e3a1000, 0x1ec08, 0xfe8ae3fc), \ at 0xff34b504 [6] INTdaemon_dorestart(0x1, 0xff272ffd, 0xff2abc04, 0x862d58, 0xfcbd40e8, \ 0xff2a2c00), at 0xff0ffb84 [7] WebServer::Run(0x1, 0x0, 0x6, 0x88108, 0x3d, 0xff272ec9), at 0xff1a5d5c [8] main(0x9, 0xffbff47c, 0xffbff4a4, 0x21400, 0x0, 0xfd035000), at 0x10fd4

  This problem occurs with all Application Server 8.1, 8.2, and 9.x when run on Web Server 7.x, and is caused by a duplicate entry for .

  Init fn="load-modules" shlib="libj2eeplugin.so" shlib_flags="(global|now)" Init fn="init-passthrough" ##END LB Plugin Parameters Init fn="load-modules" shlib="libj2eeplugin.so" shlib_flags="(global|now)"

• Solution

  Remove the first of the duplicate references to libj2eeplugin.so in the Web Server magnus.conf file and then restart Web Server.
