|Affected OS Type
||Affected Release Number
||CTIOS Server assertion; CServiceBroker::RemoveObject() FAILED|
||Multiple calls seen on CTIOS desktop during load|
||CTIOS Server stops accepting new connections after "unknown exception"|
||Ctios server reloads during outbound load creating minidump.|
||CTIOS Server show Established before Delivered causing grayed icons|
During high call volume in production, CTIOS may restart or assert with a minidump, failure to accept new client connections due to previous exceptions that may cause agent login failure, button enablement issues related agent state or call control. If CTIOS Server node did not restart automatically, it may need to be cycled via Cisco ICM Service Control to recover from this condition.
Note: We have observed the problem to be more frequent, exposed under load with variable degree of agent counts and call volumes depending on customer environment and call flows
The problem which causes the CTI OS to generate exceptions and crash was introduced in 7.2(7).
Potential symptoms of the problem addressed by ES5 are :
1) Generation of many exceptions will corrupt the memory and eventually will lead to CTI OS Server crash.
2) During load CTIOS server crashes
3) The CTIOS Server will stop allowing any more agents to connect/login
4) CTIOS Server on other side of PG only show connection to client being lost
5) Timing issue on CTIOS server causes two call connections to be created for the same device which results in greyed out icons on the ctios desktops
The following is an example of a CTI OS server log showing multiple exceptions:
08:46:11:383 CTIOS1-ctios Trace: CServiceBroker::RemoveObject() FAILED, Object(05D36008) was not found.

This issue will be resolved in CTI OS Release 7.2(7) and greater. The solution to this issue for earlier releases of CTI OS is to install the appropriate software engineering special (ES).
On systems that are running CTI OS Servers Release 7.2(7), install CTI OS 7.2(7) ES19.
CTI OS 7.2(7) ES19 can be downloaded from: CTIOS7.2.7_ES19.exe
On systems that are running CTI OS Servers Release 7.5(4), install CTI OS 7.5(4) ES3.
CTI OS 7.5(4) ES3 can be downloaded from: CTIOS7.5.4_ES3.exe
On systems that are running CTI OS Servers Release 7.5(5), install CTI OS 7.5(5) ES2.
CTI OS 7.5(5) ES2 can be downloaded from: CTIOS7.5.5_ES2.exe
On systems that are running CTI OS Servers Release 7.5(6), install CTI OS 7.5(6) ES5.
CTI OS 7.5(6) ES5 can be downloaded from: CTIOS7.5.6_ES5.exe
