Re: MCH3402 received when calling getHtmlIfsMult

Good question, Greg. I ran into that, also, with large spreadsheets. These are fairly small HTM files, though. And there weren't many in the job until the error occurred. And this user is the only one getting this.

There is a more recent WrtSectionToStmf that gets around that limit - we are behind on releases, so I've been using WrtHtmlToStmf() early on, then AppHtmlToStmf() occasionally - both are supposed to clear the HTML buffer.

Weird stuff!

Thanks

Vern - I've seen this before with WrtHtmlToStmf()... it was a 16mb memory issue.

I had to instead "break up" my process to use WrtSectionToStmf()

This "chunked" the writing into smaller pieces... This only happened when I was building very large spreadsheets.

Could be related?

Subject: MCH3402 received when calling getHtmlIfsMult

Y'all

We have one user who gets an MCH3402 a couple times a week when creating
receipts - the programs uses CGIDEV2 to create HTML files used to email.

It seems to happen after a busy morning of this. And it is to only 1 user.

Generally, the program does things in this order -

getHtmlIfsMult (only 1 template, though)
clrHtmlBuffer
updHtmlVar/wrtSection as needed
wrtHtmlToStmf

There is no information in CGIDEBUG that helps.

MCH3402 generally means that something a pointer points to is gone,
right? But it has to be in the getHtmlIfsMult.

I don't think we are running out of memory, and that isn't the cause for
MCH3402, is it, anyhow?

Our solution right now is to wrap a monitor/endmon around the call to
getHtmlIfsMult, display something to the user, then back to the caller.
They are able to go to a different app and resend the receipts.

OK, enough, TIA
