config load failure when iRule contains regsub

Has anyone seen this or know of a work-around?

When we have the following line in our iRule, the "b load" (or bigstart restart) command fails:

regsub -all {\n} $certStr {} certStr

Something with the brackets causes a syntax error. It also seems to occur when there is more than one occurance this regsub command in the iRule. Just one occurance loads fine.

Thanks!

    Yes, we know about this bug. I believe it has been fixed, but the work around is easy. Simply make sure there is always at least a space between open and close curly braces.
    eg: { }
not: {}

    Hi unRuleY, just wanted to clarify that the { } solution will not work in my case as this will insert whitespace that I am trying to remove.

     

     

    Joe, I tried your solution, it works! Thanks.
