Do you really mean asyn 4.9? If so that is almost 10 years old and 21 releases behind the current release!

Thanks for your respond.


Yes, it is the exact error message. however, I try to solve the problem by deleting the asyn, ipac and gensub folder respectively and change another path and recompiling them again. Now, they work well.

The version of EPICS base is 3.14.12.5, ASYN is 4.9, IPAC is 2.14, gensub is 1.6 respectively.

主题: Re: Question about "Link A array too large"

What version of EPICS base, asyn, and modbus are you using? I cannot find any error messages in base 3.14.12.5 that contain the string "array too large". Is that the exact error message you are getting? Since you are getting a core dump you can run gdb on the core file to see exactly where it is crashing.
