ACC Release Notes for the B.03.01 Release

Advanced Communications Controller Release Notes for the B.03.01 Release

Known Problems and Workarounds for ACC Products

• The Fast Select facility code is being dropped by the X.25

driver.

• X25ping utility does not work.

• The x25init -a ipmap command (without the -c

option) does not work.

• The swremove command may fail. When removing the

Z7476AA product from the system, you may get an ERROR

condition. Please ignore the error if the

/var/adm/sw/swagent.log shows the following message:

* Removing zx25d_init from /opt/acc/cfg/zmasterd_list

* Disabling firmware keys for ACC X25 firmware

Usage: /opt/acc/bin/fwkenb_x25 [-k <key_file>] [-i] [p] [-v] [-d | -e]

ERROR: The “unconfigure” script for “ACC-X25.ACC-X25-FW” failed (exit

code “1”). The script location was

“/var/adm/sw/products/ACC-X25/ACC-X25-FW/unconfigure”.

• Logging 64-bit values using zcomlog( )

zcomlog() allows any application to log messages with

arguments into the ACC log ﬁles. zmlog internally uses

sprintf() to substitute the argument values into the message

text before logging. Due to the technical difﬁculty with sprintf()

in supporting arbitrary 64-bit values, such as

ZCOM_AT_INT64 or ZCOM_AT_UINT64, zmlog can only

display the lower 32-bit value for these 64-bit arguments.

A program may call zcomlog() with 64-bit arguments, e.g. using

Zc_INT64(value), but the message text should use 32-bit

conversion speciﬁcation, such as %d, for such arguments. %ld

or %lld should not be used. When this technical problem is

resolved in the future, the message text can then be modiﬁed to

accommodate 64-bit conversion speciﬁcation.

• zmlog detects corruption in ZCOM log buffer

Occasionally, when zmlog reads an ACC log buffer from the

LDM driver, the read return length is not consistent with the

“log buffer length” kept in the returned log buffer. This usually

happens when there is a lot of messages being logged in a short

period of time, for example, during system start up with a large

number of X.25 circuits. But it also happens with a smaller
