[BioC] error "Too many pushAbortHandlers, can only handle 11" while exporting bedGraph/bigWig using rtracklayer from Bioconductor

[Cook, Malcolm]

Hi,

I'm not sure whether to address this to BioConductor project or the UCSC.

I am on occasion receiving the following error

error "Too many pushAbortHandlers, can only handle 11" 

while exporting bedGraph/bigWig using rtracklayer from Bioconductor using the rtracklayer

I see that this is coming from the errabort module of jim Kent, which I assume rtracklayer is wrapping/invoking.

it seems intermittent or usage related, so it is difficult to fully characterize. 

The same call to export will fail, and then succeed, after restarting R.

Any advice for sleuthing/correcting/workingAround much appreciated.

Cheers,
