System limit for number of file watchers reached when using millions of reads

[jagos01]

when running rampart with a large number of reads (~2 milion) I get the following error:

(node:13233) UnhandledPromiseRejectionWarning: Error: ENOSPC: System limit for number of file watchers reached, watch '/home/data1/Raw_Data/ncov2_seq/Z444_Zymo/ghac_4.5.4-2/pass/fastq_runid_0792bc9fc34b63218e65ffa397ba92c0fa945c17_2299_1.fastq'

This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag --unhandled-rejections=strict (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 2178)

Do you have any suggestions on how to resolve this issue?
Thanks,

Hi there. We are getting a similar error with about 1.75 Million reads. Any pointers welcome.
